The twentieth century saw several waves of interest in special function theory.

He has to his credit more than 90 research articles in complex function theory and Multimedia.

Kaczynski's specialty was a branch of complex analysis known as geometric function theory.

His fields were mathematical analysis, function theory, algebra and number theory.

The "best models" can be very different from those taken directly from elliptic function theory.

Cauchy is most famous for his single-handed development of complex function theory.

Then the function theory is enriched by sequences and series.

The result is known as Issa's theorem in complex function theory.

However, the theory falls well short of function theory on the ordinary complex plane.

He also described some of the function theory of the bireal variable.
